interval" – high and low tide simulation
"
The interval operation between low tide (pump outputs "channel" 1 / 2) and high tide (pump outputs "channel" 3 / 4)
enables two annular flows within the aquarium. The reef rock is regularly flooded from both sides, the sediments are
washed away and the invertebrates exposed to current from all directions. We recommend setting the same pump
power on both channels if possible.
In the field "mode", click on the "interval" button.
Set the interval time between 1 minute and 12 hours by clicking on "interval time" clicking, whereas 6 hours would be
the optimal setting to replicate nature.
In the field "power control", the pump performance can be set to "low power" and "high power" by clicking on "channel"
in the channels 1 to 4. The number zero "0" means pump not operating. The lowest possible setting is 20%, and the
maximum adjustable setting is 100%.
The pulse frequency "pulse flow" can be set from 0.3 to 8.0 sec. This pulse frequency is very accurate, and can also
function as a Wavebox controller. The wave motion simulation can also be switched off at a pump output through a
simultaneous "low power" and "high power" setting. For example, both settings can be 60%, which would cause the
pumps at this output to have a consistent performance, and the pulse mode would be deactivated.
Following function can be activated in the field "minimum flow for switched off pumps": The circulation pumps are no
longer completely mutually switched off, and there is a variation between a freely selectable performance and minimal
performance (20%) of the pumps. However, a minimum current flow will always persist, for example, through the
operation of the pump in a filter system.
Up to four pumps can be connected directly. With two Y-adapter cables 7090.300 an extension up to eight pumps will
be possible.
